Why does my nose run when we get a cold?

Your nasal membranes make mucus – aka snot – and this sticky substance serves as security against germs, dust, and pollen particles that would make breathing difficult if they reached our lungs. Moved along by tiny nostril hairs called cilia, snot pummels and pushes invading particles toword the exit – your nostrils – or dumps them down your throat. Your body produces nearly wo gallons (7.6 L) of mucus each week. You usually swallow all that snot without giving it a second thought. Catch a cold virus or come under an allergy attack, however, and the membranes pump up the volume. Your nose turns into a leaky snot faucet. You start coughing up globes of phlegm – a type of mucus produced in your throat and lungs. A hacking cough and runny nose are your body’s ways of flushing all the bad stuff.

  • Get vaccinations for all the major germ based illness from your doctor. Vaccine contains trace amounts of ( or weakened )microbes that trigger your body into making antibodies to fight against specific diseases, making you immune to them.
  • Be careful about sharing food or drinks with sick friends.
  • If you get sick, remember : the inside of your elbow makes a great sneeze shield. You might coat your arm in snot, but at least you will avoid infecting everyone in your launch zone.

How are germs spread?

Every time an infected person coughs or sneezes, he or she spreads sickness. One sneeze alone can launch thousands of germ-jammed droplets nearly 20 feet (6m), potentially infecting anyone in the blast radius. Bacteria and some viruses can survive for a short time on door handles, bathroom counter, and other surfaces.
